Spark Discharge Apparatus

Product Code : EL-AS-10822

Quick Answer: Spark Discharge Apparatus demonstrates the ionisation of air by alpha particles: as an alpha source is moved along the brass mesh, a shower of sparks and a crackling sound follow the source.

Last updated: October 2026

Key Features

Brass mesh above a conductor
Alpha particles ionise the air, forming a conductive path from the mesh to the conductor
Visible shower of bright sparks with an audible crackling sound
Sparks follow the source as it moves along the track
Operating instructions included

About This Product

As the alpha source passes along the mesh, the ionised air forms a conductive path to the conductor below, producing sparks that track the movement of the source. The apparatus needs an alpha radioactive source, an EHT safety lead and an EHT (5 kV) power supply. Export supply of the Spark Discharge Apparatus can be arranged to laboratories and schools in Mongolia, Tajikistan, Honduras, Botswana, Kuwait and Malawi.
